WATER-HEATER.

Specification of Letters Patent.

Patented Aug. 15, 1916.

Application filed June 2, 1915. Serial No. 31,729.

To all whom it may concern:

Be it known that I, JOHN B. GRANT, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Tater-Heater, of which the following is a specification.

The present invention appertains to water heaters, and aims to provide a novel and improved water heater adapted to be interposed between a stove, range, or the like, and the stove pipe, whereby the products of combustion are directed through the present appliance for heating the water.

It is also the object of the invention to provide a water heater which is improved in its construction and details, to enhance the utility thereof.

Another object of the invention is the provision of a water heater having the features above noted, and which is also comparatively simple, compact, non-encumbering, and inexpensive in construction, as well as being convenient, practical and efiicient in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a longitudinal section of one form of the invention. Fig. 2 is an upper end view of the first form. Fig. 3 is a cross section taken on the line 33 of Fig. 1. Fig. 4 is a lower end view of the first form. Fig. 5 is an enlarged sectional detail taken on the line 55 of Fig. 3.

In carrying out the invention, reference being had to Figs. 1 to 5, inclusive, there is employed an upright cylindrical casing 1 constructed of sheet metal or other suitable material, which is provided at one side with a door way or opening 2, which is normally closed by a door 3 of arcuate cross section. The door 3 is preferably constructed of sheet metal, and the casing 1 and door are preferably lined with asbestos or other fire proof and refractory material.

The upright edges of the door 3 overlap the outer side of the casing 1 beyond the side edges of the opening 2, and the upper end of the door 3 is provided with a reduced portion 4 slipped upwardly into the casing 1 so as to project above the upper end of the opening 2 and fit snugly beyond or within that portion of the casing 1 above the openmg. The lower end "of the door 3 overlaps the exterior of the casing at the lower end of the opening 2, and a plurality of latch members 6 are riveted or otherwise secured to the inner side of the door 3 adjacent the lower end of the door, and are provided with depending inwardly offset portions 7 which engage downwardly over the inner side of the casing 1 below the lower end of the opening 2. In assembling the door 3 with the casing 1, the reduced upper end portion 4 of the door is first slipped into the casing at the upper end of the opening 2, and the door 3 is then lifted or shifted upwardly sufiiciently, so that the ofi'set portions 7 may be moved inwardly over the lower end of the opening 2, in which event, the door 3 is shifted downwardly slightly so as to engage the portions 7 behind or within the portion of the casing 1 at the lower end of the opening 2. The portions 7 and lower end of the door3 thus straddle the portion of the casing 1 at the lower end of the opening 2, and the upper end portion of the door in fitting within the casing, will serve to effectively hold the door 3 in place. To remove the door 3, the door is lifted slightly so that the lower end of the door may be shifted outwardly slightly so as to become disengaged from the casing, in which event the door may be lowered. Particular attention is directed to the fact that the door 3 may be readily applied to and re moved from the casing 1 within a small space, and which is especially desirable when the use of a hinged door would not be practical. The door 3 is provided upon its outer side with a suitable handle 8 between the ends of the door whereby the door may be conveniently manipulated.

An upright water circulating and heating coil 9 is disposed within the casing 1, and its upper and lower ends extend through the walls of the casing for connection with a common or suitable water tank or reser voir. The upper convolution of the coil 9 is embraced by a doubled bar 10, having a bolt 10 engaged therethrough for causing the bar 10 to embrace the upper convolution of the coil, and one end of the bar is bolted or otherwise fastened to an inwardly projecting bracket or arm 11 secured to the upper end of the casing 1. The lower convolution of the coil 9 is embraced by a doubled bar 12 which has its ends secured in any suitable manner to the lower end poi tion of the casing 1. The coil 9 is thus supported properly within the casing, and it will be noted that access may be had to the interior of the casing when the door 3 is removed, and when the door 3 is removed, the coil 9 may be readily removed or inserted through the opening 2.

A reducing collar 13 of sheet metal or other suitable material is secured in any suitable manner to the upper end of the easing 1, and is provided with a reduced circular nipple or free end 1 1, over which the end of the stove pipe 15 is adapted to he slipped, a damper 16 being preferably mounted within the collar 13 to control the draft, and to hold the products of combustion within the casing 1 when the damper is closed. A reducing collar 17 is also secured in any suitable manner to the lower end of the casing 1, and is provided with a reduced nipple or free end 18 of elliptical contour, whereby the said nipple is adapted to engage the elliptical outlet portion or flange of a stove, range or the like. The ends of the casing 1 are thus provided with any suitable means for engaging the stove, range or the like, and the stove pipe, whereby the present device may be readily installed on various stoves, ranges, and the like, and

whereby when the device is installed, the products of, combustion will flow through the casing 1 and coil 9. The water in circulating through the coil 9 will be heated by the products of combustion, whereby the products of combustion are not entirely wasted, but are utilized for heating the water.

Having thus described the invention,what is claimed as new is:

i A water heater comprising an upright cylindrical sheet metal casing having an opening at one side, a sheet metal door of arcuate cross section having its side edges overlapping the outer side of the casing at the side edges of said opening, the upper end of the door having a reduced portion fitting within the casing'at the upper end of said opening, the lower end of the door overlapping the outer side of the casing at the lower end of the opening, and members attached to the inner side of the door adjacent the lower corners thereof and having inwardly ofl'set portions engageable downwardly upon the inner side of that portion of the casing at the lower end of said opening and adjacent the side edges of said openmg.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

JOHN BAIN GRANT.
